MODE 0F CONSTRUCTING CAST-IRON BUILDINGS.

Specification of Letters Patent No.

To all whom t may concern:

Be it known that VILLIAM D. TERRY, deceased, did in his lifetime inventcertain new and useful Improvements in the Construction of Cast-IronHouses; and that I, HARRIET V. TERRY, of Boston, in the county ofSuffolk and State of Massachusetts, administratrix of the estate of thesaid VIL- LraM D. TERRY, do hereby declare the following to be a full,clear, and exact description of the aforesaid invention, reference beinghad to the accompanying' drawings, making a part thereof, in which-Figure l, represents in perspective, several of the sections placedtogether, or laid up. Fig. 2, represents a top view on a reduced, andFig. 3, a similar top view on an enlarged scale, of the manner in whichthe sections are joined, or locked together. Fig. 4, represents inperspective, a modification of the general plan, and Fig. 5, a top viewof said modification.

Similar letters Where they occur in the several figures denote likeparts.

To enable others skilled in the art to make and use the invention, Iwill proceed to describe the same with reference to the drawings.

A, A, and B, B, represent rectangular cast iron sections, the formerbeing much higher than the latter to show that, the size of thesections, is limited only to the facility of molding and casting them.These sections are in the form of oblong boxes, open at both ends, whichopen ends, when the sections are laid up, are at the top and bottomthereof. The outer sides of these sections, project beyond the endssufficiently far to form a rib a, and on the said ends, parallel, or asnearly so as practical, to the ribs a, are formed other ribs b, the tworibs being far enough apart to form a groove or rabbet c, between them.

O, C, are metal plates, having an L-shaped tongue l formed at each oftheir ends, which tongue slides into the rabbet c, formed in the ends ofsaid boxes, the tongues and rabbet-s being so placed as to admit of theoutside of the sections, and of the plates being flush with each otheras shown in the drawings, and thus by alterby piling one set uponanother. The walls will of course be hollow, and the open 14,208, datedFebruary 5, 1856.

spaces between them may be used for flues of any kind.

To bind the sections and plates together, a tie piece D, may be used,which has two sets of rabbets, into which, the tongues may be slipped asshown in Figs. l, 2, and these tie pieces may be introduced into thewalls, as often as may be deemed necessary, to properly tie themtogether.

To make the joints between the boxes and plates perfectly tight, anadditional rib e, Fig. l, may be formed on the plates, over which thebox-sections may pass, and white lead, or any other cement, may beintroduced at the joints, as the walls are laid up, to make themperfectly tight.

For making the corners, or cross walls of the building, some of theboxes are formed withribs f, f, on their sides, with a rabbet c',between them similar in all respects to the ribs and rabbets on the endsof the said boxes, and the plates are slid into these side rabbets, andthus form a right angle in the wall, as seen in Fig. 2.

Figs. t and 5, represent a modification of the above described plan, inwhich, instead of casting the box, and plates separate, as shown, onehalf of the box, and one plate, are cast together or in one piece,forming as it were a double right angled piece. When two of these doubleright angled pieces, are laid together, as shown in Fig. t, they formprecisely the same figure, that the box and two plates, would form ifsimilarly laid together, and are consequently but modifications of eachother. The double right angled pieces, may have but a single rib, asshown, or they may be like those on the boxes, in which latter casehowever the L-shaped tongue would have to be introduced also, to makethe joints smooth and even. In molding these sections, it will benecessary to make the ribs slightly tapering or wedge formed, so thatthe patterns will draw from the sand. This, when t-he taper is on thecontiguous sides of the ribs, will make the rabbet wedge shaped also. Bygiving the same taper to the tongues that fit into these rabbets, thejoints will be equally tight, as though there was no taper on either.The inclination may all be on the outsides of the ribs, and then therabbet and tongue may be straight. In either of the cases, the castingsare provided With the devices which serve as the astenings to hold themfirmly together in the Wall, Without the aid of rods, bolts, keys, orany other separate fastening.

In forming doors or Windows any suitable number of the boXes or platesmay be left out. And to make the building en tirely of iron, and fireproof, the partitions, floors, and roof, may be of iron also.

Having thus fully described the invention of the said WILLIAM D. TERRY,de-v ceased, I Would state that I do not claim the boxes and ties, whenused separately as this has been done before, but

wWhat is claimed herein as new, and de- 15 sired to be secured byLetters Patent is,

The forming of cast iron, holloW Walls for buildings, by means of thecombined use of the boxes, plates, and tie pieces, provided With rabbetsand tongues, for firmly unit- 20 ing them together, substantially in themanner described and represented.
